FAUCET AND PROCESS OF MAKING SAME.

Application filed October 11, 1928. Serial No. 311,818.

This invention relates to faucets particula rly adapted for application to water service lines. A principal object of invention is to provide a simple and economical, leak-proof faucet arranged to be quickly opened and closed and having a valve therein opposed to the passage of a liquid therethrough, so that the pressure on will serve to seat the valve and prevent leaka ge of the liquid from the spout under normal conditions.

A principal object of invention also is to provide a faucet having an integral body and spout so designed that it may be die-cast in molds for the purpose of reducing the manu facturing cost, and further to provide a process for producing faucets by die-casting. In order that this may be done, it is necessary to so arrange the openings in the body that cores maybe withdrawn from the mold subsequent to a casting operation, and at least one of said openings may be closed permanently to present a finished appearance to the faucet.

Heretofore in the construction of faucets it has been found necessary to sand cast the faucets, and it is well known that castings produced in this manner require a substantial amount of finishing in order to polish and plate the-castings. The obtaining methods are therefore expensive and the weight 'of the finished article is usually excessive.

Accordingly, it is an object of my invention to provide a type of faucet which can be molded in a die casting operation of a suitable metal, so that when completed a minimum expense only is necessary in finishing castings preparatory for use, and the finished article will be of minimum weightand consequently made at a minimum expense.

Itis a further object of this invention to provide a faucet which is free from unnecessary and complicated parts, gaskets, washers and the like, which are susceptible to wear and corrosion and consequently cause trouble in the operation and use of the faucet.

This application is a continuation in part of my application, Serial Number 242,589, tiled December 27, 1927, for faucets.

The details of my improvements will be hcreina fter explained, and are shown clearly in the appended drawings, in-which:

Fig. 1 is a sectional elevation of a faucet embodying my improvements;

the inlet side of the faucet Fig. 2 is a sectional plan of the same on line 2-2 of Fig. 1.

Fig. 3 is a sectional plan of the same on line 3-3 of Fig. 1.

Figs. 4 and 5 are the body of the faucet showing the method and means for closing one of the core recesses in the bodyby means of which the passage in the spout of the faucet is cored in a die castlng process.

Fig. 6 is a sectional elevation of a faucet after the casting operation but before the cores have been withdrawn.

Fig. 7 is a section on the line 7--7 of Fig. 6. Fig. 8 is a detail showing one form of a core used in my process of making a faucet. Referringto the drawings, the body 10 has a flanged bottom portion 11 adapted to" rest against a suitable supporting member for the faucet, such as a wall or a basin. From the base of the body 10 is extended an integrally formed threaded stem 12 having an inlet passage 13 therein communicating with an inlet chamber 14. which is in turn in communication with central chamber 15 in the body 10. It will be noted that the inlet passage 13, inlet chamber 14 and central chamber 15 are preferably concentric and of progressively greater diameter, forming annular shoulders or ledges 16 and 17, shoulder 16 being formed between inlet passage 13 and inlet chamber 14, while shoulder 17 is formed between inlet passage 14 and central chamber 15.

The body 10 has an integrally formed spout 18 extended at right angles to the axis thereof, with an angularly formed delivery nozzle 19. The spout 18 has a cored passage 20 formed therein which opens into the chamber 15 of the body and is transversely alined with an opening 21 formed in the wall 22 of the faucet body. This openin 21 is in communication with central cham er 15 and positioned diametrically opposite spout 18, the passage 20 and opening 21 being of circular, elliptical or any other cross-section, depending upon the desired form and shape of faucet spout. The opening 21 may be left unsealed as by my construction no water can pass into opening 21, thus rendering it unnecessary to seal the same against leakage of water therethrough. However, for the sake of the appearance of the finished faucet the opening 21 may be sealed in any suitable manner. As

fragmentary sections of shownin the drawings, the openingis sealed by means of a disc 23,- which is .formed of sheet metal, may be of circular, elliptical or other outline, and is of concave cross-section, as shown in Fig. 4.

The outer side of the bedy'wall 22 is'countersunk at the opening 21 to provide the annular shoulder 24 and cylindrical inner wall 25 of a counter-recess 26 of slightly greater diameter than the opening 21. Member 23 when positioned as shown in Fig. 4' is forced inward-1y against shoulder 24 by means of a suitable die or tool until it assumes a fiat cross-section, as shown in Fig; 5.

In the closing operation the flattening of the member 23 will cause the edges of said.

member to cut an annular groove 27 into the cylindrical wall 25 thereby firmly seating the.

same in the metal at the periphery of the counter-recess 26 and against the shoulder 24, so as to form a permanent closure for the opening 21. It .will be understood, of course, that the member 23 is of substantially harder and denser metal than the die casting metal of 'which'the faucet is made.

The bodylO has an internally threaded nipple 28 which is adapted to receive an externally threaded portion 29 on thecap 30, so that said cap may be threaded into the portion 28 until the hexagonal portion 31' of the cap abuts the outer end of said portion recess 37 formed within the portion 29 thereof, providing a shoulder 38. A head 39 carried on the mner end of the stem 33 ad acent the screw 32 is movable in the recess 37 means of a key, as at 41 in Fig. 2. 40 is arranged to slidably support a valve 42 and may be retracted upwardly against shoulder 38 by means of screw 32 operated by handle 34.

The valve supporting member 40 is held against upward movement in central chamber 15 by means of screwing down cap 30 to abut the upper end of member 40 thereby forcing the member 40 downwardly to seat the lower end of member 40 on a gasket 40' resting on shoulder 11 to make a water tight joint, preventing fluid from inlet chamber 14 passing up into opening 21 around member 40. The valve supporting member 40 is stationarily held against rotary movement in central chamber 15 of the-bodgflO by ember having a stem 43 and has a tapered valve seat 44 adapted to receive and seat a valve packthrough passageway 48 of delivery nozzle 19,

when the valve is open. By means of the key 41, the port 47 is positively alined with the spout passage 20.

The stem 43 of valve 42 is slidably held in a bore 49 in the upper portion of member 40, and when the valve 42 is closed, as shown in Fig.1, the upper end of said stem 43 will.

project upwardly into the chamber 37 of the cap 30 so as to be readily engaged by the head 39 of stem 33 when the handle 34 is operated for screwing the screw 32 inwardly in the cap 30.

Valve 42 is operated in opposition to the pressure of water in the passage 13 and the chamber 14, which serves to normally hold the valve closed, as shown in Fig. 1, when the handle 34 is in open position and the head 39 connected therewith is disengaged from the valve stem 43.

A particular feature of the present invention is the provision between the members 30 and 40 of a shallow chamber 50 in communiof the member 40 and extending downwardly at an angle,.so that when water is flowing through the member 40 and outwardly through the spout passage 20, a flow of the water from the chamber 50 will be induced and said chamber will be relieved of any pressure which might otherwise be created therein, and which would serve to prevent the complete closing of thevalve 42.

Referring particularly to the steps involved in producing my faucet, I locate cores 60, 61, 62 and 63 in a die-casting inold in the position shown in Fig. 6 of the drawing. As shown in Fig. 6 of the drawing, the core 60 is so positioned as to form the central chamber 15 in the body 10 of the faucet, while a core member 64, integral with core 60 forms the inlet chamber 14. As indicated in Fig. 6 the core 60 has an opening therethrough which may be elliptical in cross-section as shown at 65 in Figs. 6 and 7 to receive elliptical cross-section core 62 or may'be circularin cross-section to reeelve a core 66 of circular cross-section as shown in F ig. 8 of the a cheap product, economical both as to time drawings or may be of any other desired cross-section depending on what cross-section is desired for the spout 18. The core end 67,

integral with the core 62, extends through and projects a short distance beyond the core 60, so that the one-piece core 62 forms the spout passageway 20 and simultaneously also the opening 21 in the body wall 22.

The opposite end of the core 62 has a mitred face as indicated. by 68. Abutting this mitred face 68 is the mitred 'face'69 of the core 63 which forms the curved or bent terminal portion 19 of the spout. It will be understood that each of the cores 63 and 62 has a slight draft to permit ready removal thereof after the casting operation which is likewise facilitated by reason of the angular portion 7 O at the point where the curved terminal portion merges into the straight portion of the spout to permit the withdrawal of the core 63 towards the left as shown in I the drawing. The core 61 is preferably separate from the core 64 which is integral with core 60, in which case 71 indicates the line on which the abutting faces of the two cores 61 and 64 come together. However, the cores 61, 64 and 60 may be all formed integral and withdrawn in one piece in an upward direction looking at the position of the parts illustrated in Fig. 6.

After the molten metal has been poured in the mold around the cores, the cores are removed in the following order. The core 62 is first withdrawn toward the left through the opening formed in the core 60 and through the opening 21 in the bodywall 22. Simultaneousl the removal 0 this core 62 the terminal core 63 may be removed. After the core 62 has been withdrawn the core 60 is free to be withdrawn upwardly, carrying with it the core 61 in case these cores 61 and 62 are made integral. In the event of core 61 being separate from core 60,'core 61 would be withdrawn downwardly whereas core 60 with its integral part 64 would be withdrawn up'wardly as seen in Fig. 6.

Particular attention-is called to the diecasting of a spout orifice in the form of a radius or curve, as shown in the drawing by the spout l8 and orifice 19 of a faucet, by means of the use of steel cores.

It is desired to emphasize especially one of the features of my invention and that is the die-casting of a hollow curve or radius that is necessary in the casting of a faucet that requires the usual curved spout o'r outlet for the liquid.

()u the other hand. by my invention, I have made possible the withdrawal of a straight core through the body of the faucet, necessitating an opening in the body which can be .-ealed h an expansion plug or screw or threaded plug or other suitable means.

or prior or subsequently to.

By iny invention, I am enabled to produce and material used and producing a finished article In one operation-not possible by old methods hitherto employed in this'art.

By my die-casting process, faucetsmay be produced at a maximum quantity production with a minimum of cost, eliminating the necessity of costly machining and finishing operations hitherto necessary in the case of sand castings and resulting in a perfectly formed formed in any other way. I

Thus, it will be observedthat I vided an improved type of faucet embodying characteristics of deslgn not heretofore used or employed in such devices, and that the structural arrangement and details thereof are simple and capable of ready adjustment and dis-assembling for necessary repairs or faucet of appearance superior to faucets adjustments.

have 1 pro- I conceive it to be possible to modify the 2 structure within the scope of theappended claims without departing from the spirit of my invention.

Whatl claim is:
